💅 rxe_mcast_del(9) — the kernel API manual, bestie edition

okay so this is rxe_mcast_del, and it lives in the Kernel API Manual. Yes, the whole manual. It's a function, it's in section 9, and it's about to delete a multicast address off an rxe device. Iconic behavior honestly.

✨ NAME ✨

rxe_mcast_del — delete multicast address from rxe device

Like, the entire job. Take the multicast address, yeet it off the rxe device. That's the gig. 🎀

🌸 SYNOPSIS 🌸

int rxe_mcast_del (struct rxe_dev *rxe , union ib_gid *mgid );

That's the whole signature, copy it exactly, no cap. 💖

🦋 ARGUMENTS 🦋

  • rxe — the rxe device object. your little device guy. the one we're operating on 🫶
  • mgid — the multicast address, but as a gid. yes, a gid. that's the form it wants 💅

🔥 DESCRIPTION 🔥

Returns 0 on success, else an error.

That's it. That's the description. Not me expecting a whole novel and getting one line 😭 but honestly? it's giving confident-and-brief, and we respect it. So: success gets you 0, anything that isn't success gets you an error instead. periodt. ✨
